Abstract: A method for mapping distribution of chemical compounds in soil is described herein including inserting a probe into the soil, obtaining spectroscopic data regarding the soil, sampling a core of soil adjacent to the probe locations, dividing the core into multiple depth increments, analyzing the core samples, matching each core sample with a corresponding depth increment of the probe insertions, obtaining data from the probe insertions, dividing the probe insertion data into training, validation, and test categories, resampling spectral variables from the probe insertion data to a wavelength interval longer than a native wavelength interval of an associated spectrometer, normalizing the probe insertion data on a spectrum by spectrum basis, utilizing a machine learning normalization algorithm, standardizing the spectral variables to a common scale by removing a mean and scaling to unit variance, and choosing a model utilizing the test set.

Abstract: Provided is an optical measurement apparatus including: a polarized light irradiation unit 10 that irradiates a subject Ob with irradiation light of which polarization is controlled; and a polarization imaging unit 20 that images a polarization state of measurement light occurring due to scattering, reflection, absorption, or the like of the irradiation light by the subject Ob, calculates all or a part of Stokes parameters of the measurement light, and measures a variation of a polarized component occurring between the irradiation light and the measurement light due to the subject Ob. Since the subject is irradiated with irradiation light of which a polarization state is controlled, it is possible to acquire subject information that is difficult to measure in a case of irradiating the subject with natural light, that is, non-polarized irradiation light, and it is also possible to suppress noise or a decrease in contrast that occurs when measuring polarization by irradiating the subject with irradiation light of which a polarization state is unstable.

Abstract: A system comprising a nonlinear medium (NLM), an optical transduction module, a dual homodyne detector and a processor is provided. The NLM receives at least a pump beam and issues the pump, probe and conjugate beams, where the beams are linearly polarized. Optics route the probe, the conjugate or both beams to the sample. The sample imparts polarization rotation to light that interacts therewith. The optical transduction module imparts to the interacted light an optical phase shift that is a 1:1 transduction of the polarization rotation, where at least one of the probe light or the conjugate light carries the imparted optical phase shift. The processor obtains the optical-phase shift based on respective detection signals from the dual homodyne detector and determines, based on the obtained optical-phase shift, at least one of a Faraday polarization rotation, a Kerr polarization rotation or a spin noise spectrum.
